Abstract

The fluorochrome pattern produced by DA/DAPI double staining in Pan paniscus chromosomes is reported. The location of DA/DAPI prominent bands differs from that reported for all other hominoid species. However, the pattern in the pygmy chimpanzee is most similar to that seen in Pan troglodytes. Comparison of the DA/DAPI pattern of the other hominoid species allows the construction of a proposed hominoid ancestral karyotype and a preliminary phylogenetic reconstruction of DA/DAPI bands for the great apes and man.
